REFRIGERATING SUPPLY SYSTEM Russian patent published in 2001 - IPC

FIELD: refrigeration supply. SUBSTANCE: the refrigeration supply system has several compression refrigerating machines and several circuits. The heat-transfer agent refrigeration circuit passes through successively positioned evaporators of the refrigerating machines to the using equipment. From the using equipment the circuit passes through the third pumping plant, which through a heat exchanger is connected to the outlet of the last evaporator. The refrigeration circuit is made closed and passes through successively positioned condensers, the second pumping plant, block of radiators and a valve. The refrigeration circuit of the condensers is provided with an additional circuit connecting the outlet of the block of radiators to the inlet of the second pumping plant and passing through the valve and heat exchanger. The water refrigeration circuit has successively installed in the direction of water flow the first pumping plant, heat exchanger and a using equipment. EFFECT: reduced power consumption, enhanced service life of the system, and enhanced reliability of system functioning on the whole. 1 dwg
